How to build artillery

[HavocX]

Can someone explain why militia starts with artillery but I can‘t add any to regular units even after developing new models?
Arty does not appear in any of my Formations. Do I need to discover an OOB that uses artillery?

For that matter, how do I make Automated Turrets and Automated MGs?

You need to unlock them and usually it's in the independant unit list. Else you need to discover OOB

[Culthrasa]

You need to discover the models first.. Under Management - type and hover over the unit types tells you which tech you need, and you also need a model council.

Artillery comes quite quickly once you have a model council. Automatic turrets/MG require a high tier tech under the "automation" tree.

hope it helps!
